The Everything engine is available. I really love this community system and it has been an invaluable resource for me while I was (better, since I am) learning Perl. I told a friend of mine about Perlmonks and he asked me if there was a similar site for Java.

A language I'd like to know very well in its aspects is C++. I'd like to invest effort on a C++ community but I won't have time for 10 months :))
